Applanix processing instructions
Make sure you have both dongles in the PC
open POSPAC MMS
click new project / save project / type a name. ( I Use the format 20160314)
click Import icon (at top just below run) / choose folder on right/ click import
Choose both the start and roving segments and do not modify the antenna or receiver profile, leave it unknown with 0 height for both segments, click ok on the easting and northing screen too.
FOR super fast easy GNSS processing do this:
click the gold star
under the gnss mode on the right drop it down and choose primary GNSS
click run on the bottom left. Hopefully it works, if it crashes you have to chop off some seconds from the processing time
to chop off seconds, click on "Project" then "project settings" then "GNSS-inertial processor" then uncheck entire time internal, and add a couple seconds to the start time (I use 100 second intervals and keep trying it)
After the run is done, get your .out file in \documents\pospacMMS\projectname\Mission1\proc\sbet_Mission1.out take this file and rename it to our format (see near the bottom here)
To do PPP processing do this:
Click the gold star icon / under gnss mode Choose POSGNSS PPP / click yes click yes
Your files convert to rinex (takes some time)
PosGNSS opens
use windows explorer and copy the .16o and .16n (16 in this case is for the year 2016) mission files from the pospac/mission1/extract folder to the gnss folder
click convert data (beside print) and click get folder, choose the folder where you put the .16o files and the click add all on the left.
then click convert to convert the mission file to .gpb
click close close
click download service data (beside convert) / add closest tab/ position from gpb file/ choose the file you just converted (change folder!!)/ click download
[IF ftp does not work, open a browser window and refresh it then go back to ftp and click download]
click close / close
under file click alternate precise ephermis files / browse to folder and click add, select the 3 files (drag mouse box around them) the clk the sp3 and the epp from the mission / click open/ click ok
under file click remote file / choose the gpb file / do not specify an antenna just using 0 (the top option)
You do not need a master (base station) file for PPP processing
click process PPP (icon with airplane) and under general tab change elevation mask to 12 degress (or whatever you want) click apply then process.
watch your data, it should be green in the status light, red is bad.
when it finishes choose output / export to pospac
Back in pospac, under project/project setting/gnss inertial processor/lever arms and mounting angles, put in the lever arm values you measured in the reference to primary gnss lever arm. For example, on the spring DC8 they were x=+1.775 Y=+.231 and Z=-3.450. Leave the reference to IMU lever arm as zeros.
click ok and then click the gold star, chose PPP and click run.
After it gets done, go under reports/display plots and look under the calibrated installation parameters for X Y and Z. Choose X and make a box around the end of the plot and zoom way in until you can get a good value for the plot. Write this number down in a log.
Do the same for Y and Z and record this in the log.
For a campaign, you would repeat this process for each mission and get a log of values for X Y and Z then you would take the average of each offset and use that average number as your true offset. SAVE EACH MISSION AFTER YOU GET THE OFFSET FROM THE GRAPHS, YOU WILL COME BACK TO EACH.
After you find the average, go back to the first mission then go in project settings and change all the gnss lever arm values you had to zeros. Then put in the average values you calculated in the TOP section under reference to IMU lever arm. THESE VALUES WILL HAVE THE OPPOSITE SIGNS AS THEY DID IN THE REFERENCE TO PRIMARY GNSS LEVER ARM. Example, the DC8 values under IMU lever arm were X=-1.775 Y=-.231 and Z=+3.450 (see they are opposite!) Now click the gold star and run PPP processing again.
Save each mission after its processed. The main file you are after will be called sbet_mission1.out under the proc folder for each mission. Normally we would copy this file then rename it to this format, BD982_23May10_PPPK_P25May10.out this format (which is read by many in house programs) is the type of GPS receiver in the applanix (BD960) (now BD982), the day/month/year, then the type of processing PPP and the K is for kyle processed this file, if your name is Matt then you can use M or A for Alexey. the last part P25May10 means the day month and year you processed the file (todays date)
